Let G={G(x),x=0} be a mean zero Gaussian process with stationary increments and set [sigma]2(x-y)=E(G(x)-G(y))2. Let f be a function with Ef2([eta])<[infinity], where [eta]=N(0,1). When [sigma]2 is regularly varying at zero and is locally integrable for some integer j0>=1, and satisfies some additional regularity conditions, in L2. Here Hj is the jth Hermite polynomial. Also :(G')j:(I[a,b]) is a jth order Wick...</[infinity],>
